Guns in question are
AR-pistol made from Anderson parts, SW 9c, Walther PPQ.
Ammo used fiocchi, freedom munitions and tullammo.
Ar-pistol and Walther PPQ have been used for many years without any issues, but mp9c is relatively new.
The issues observed are
failure to eject. On walther the casing just gets stuck between barrel and slide, but on AR-pistol the casing is not ejected and new round is force fed into the barrel. I have to drop the mag, lock back and then pry the new round and casing with my finger.
failure to feed. With 9c one of the images shows the new round almost vertical on the feed ramp.
failure to feed? with walther after firing one of the rounds I attempted to fire again and heard only pin drop. After locking back the empty casing was still in the barrel.
Multiple times the slide wouldn't lock back on empty mag
A few instances with walther of not picking up new round.
What did I try
I tried different kind of ammo for both AR-pistol and the handguns as mentioned above.
Cleaning. I started using Eezox recently and thought maybe that had negative effect. I've recleaned using Remoil but the problem wasn't corrected.
Several magazines.
Additional data
I've also had my itty bitty SW Shield and SW Ar15 and they had no problems whatsoever. As a matter of fact I haven't cleaned them the last few hundred rounds. Still going perfect.
Not sure what to think; open to all suggestions as to what might be wrong.
